IMPROVED BED-BOTTOM.

TO ALL WHOV IT MAY CONCERN:

Be it known that I, EDWARD YEOMAN., of Waukegan, in the county of Lake, and State of Illinois, have invented an improved Bed-Bottom; and I do hereby declare that the following is a full, clear, and exact description cf the construction and operation of the same, reference being had to the accompanying drawings t and letters marked thereon, making a part of this description, in which- Figure l is a side elevation of my bed-bottom.

Figure 2, an end elevation ofthe same.

The nature of my invention consists in the use of diagonal braces jointed to an upper frame, and extending to a lower frame, at which place they are made to pass around 4and slide upon rods supporting coil springs, adjusted between lugs attached to and projecting upward from said lower frame.

My object is to combine with the common coil-spring bed-bottom a suitable number of braces arranged in such a manner as will prevent any considerable longitudinal or lateral motion of the upper section or frame, and at the same time allow it to have a fr ee vertical motion on the springs. I know that elliptical springs, vertical rods operating in coil springs, and straps have been used to accomplish this desirable end, but none of them seem to fully answer the purpose; therefore I have devised the means, hereinafter shown, which will not only prevent a lateral motion, but obviate the necessity of using as heavy springs under the mattress.

In order to give a correct understanding of my invention, I have marked corresponding parts, and will now give a detailed description.

A B represent the upper and low'er frames of the common spring-bed bottom, covered in the usual manner with canvas, J. I represent this style of bottom as being better adapted to the application of my improvement than others of a different pattern. D D D D represent what I term braces, two of which are used on each side and endof the bottom, and may be lmade either of wood or iron, as most convenient or desirable, and should be made long enough to slide on rods E, when a weight is put on frame A. h h t lt represent staples made of iron'or suitable material, and put through holes made near the upper ends of braces D, and then into frame A, in such a manner as to allow it to spring downward without cramping on the joints so formed. In the drawings Vthe braces D are represented as made of wood, and have metallic caps put over their lower ends, with suitable holes made through them for passing over rods E. These rods. are made fast to lugs ffff, Snc., secured to frame B, and pass through coil-springs used to assist in supporting the frame A, and preventing a lateral motion of the same.

It will be seen from this description that the frame A is thoroughly `braeedin every direction, and yet arranged so as to have the benefit of the common coil-springs C C, &c.

Having thus fully described my invention, what I claim and desire to secure by Letters Patent, is-

The combination of the braces D D D D-jointed to frame A, andV arranged to operate on rods E, supporting coil-springs adjusted between lugsf and C, the, whole being arranged to support and prevent a lateral motion of frame A, substantially as herein specied.

EDWARD YEOMAN.
